Question 133378
{{{3^(-x)}}} Start with the given expression




{{{1/3^x}}} Since we have a negative exponent, this means that we flip the base 3 to get {{{1/3^x}}}



{{{1^x/3^x}}} Rewrite {{{1}}} as {{{1^x}}}



{{{(1/3)^x}}} Factor out the exponent 



So this shows us that {{{3^(-x)=(1/3)^x}}}
